When a river flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flows horizontally. Find the slope of the
river shown to the right. (Hint: The slope of a river is positive.)
81 ft
372 ft

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
